The springs in these casters take on bumpy surfaces and obstructions while preventing shock to the load. Their polyurethane wheels combine the abrasion resistance of plastic with the impact resistance of rubber.

Made of hard polyurethane, solid wheels are impact resistant and roll easily on smooth surfaces, but can be noisy. Their swivels have double-ball bearings for the smoothest swiveling.

Tread-on-core wheels have an aluminum core that is harder than the tread, balancing strength with cushioning. They have a soft tread that is shock absorbing and provides good traction on rough surfaces. Their rounded treads are easier to turn than flat wheels.

Ball bearings in the wheel provide easy rolling. Their kingpinless swivel raceways distributes impact better than standard kingpin casters, enabling smoother swiveling and extending service life. They have ball bearings for smooth swiveling.

Sealed bearings are completely sealed for the best protection against dust and debris.

Optional swivel locks prevent the caster from swiveling with the twist of the ring.
